System Performance Evaluation - Siemens airanger DPL PLUS Instruction Manual

System Performance Evaluation

For initial RUN mode entry (or after any programming alteration), do not use the AiRanger
DPL Plus to operate process control equipment until satisfactory system programming
and performance is verified.
1. Press PROGRAM
AiRanger DPL Plus takes measurements and calculates the Reading.
When a Transducer (P004) value is entered for Point 1, only the Reading and other data is
displayed continuously. When Transducer values are entered for Points 1 & 2, Readings
and other data are displayed alternately. When a Point 3 Operation is entered (difference
or average), the Point 1, 2 and 3 displays scroll sequentially.
If an alarm symbol is displayed, the corresponding relay is de-energized.

* Objects close to the transducer face (0%) are not detectable.
3. Press to observe the mA output value for the Point Number displayed (Auxiliary
Reading).
Operation
Empty to Full =
* Objects close to the transducer face (4 mA) are not detectable.
4. Press to observe the Failsafe Time Left (time left in percent before failsafe
activation).
Each time a valid measurement is made for the Point Number displayed, this value
(Auxiliary Reading) is reset to 100 and begins to fall toward 0 until the next valid
measurement is made.
If the Failsafe Time Left reaches 0, the AiRanger DPL Plus flashes LOE in the Reading
display.
All associated data is supplied to the Peripheral Communications terminals (27 and 28).
